You have no idea how much you have taught me, thank you brother.
I love the way you explain stuff.
May God bless you.

[azatturegeldin]

A brilliant explanation. I was reading a book where I had a similar project with a button and a capacitor. I couldn't implement it properly, and this video helped me a lot!

[eternitysf]

You explained very well! thank you so much!

[aaronjeffery]

Your vidios in the ardiuno series are amazing.Keep it up bro

[TehnoVito]

Great video! All your explanations are slow and matcable. Great job!

[spurfy]

how did we know if we connect the LED, at the PIN + or a the - one ? Does it will change something ? Or the voltage juste will be inversed ?

[behem]

what do i need to edit in order to replace the led with variables?

[G-ROQUEPRECIOUSZOEA.]

How is it when pushing the buttons to stay on/off? Im having a science project where i need an arduino to control the temperature of my desired heat/cold. Please respond...

[amirarab]

Hello and thank you very much for the great video. Nevertheless I have a question: why do I have to connect the button anyway to the ground. When I don’t push the button, there is no current flow and the input to the PIN is low. Why is the connection to the ground necessary?
Than you

Hello i have a question, how come does my LED is turned on even, i haven't pushed the button, while if i pushed the button, it just glows brighter? i just followed the commands
TYIA!

What will happen if place the switch on one side?

And if we place switch in such a way that the legs are placed on two side.how it gets current or voltage to all legs since the two sides are separated by a plastic? insulator?

[SyntaxError-]

I have a question. Can I just make the button let the electricity flow between the LED and the GND-bus? It wouldn't need as much code

[Lucky_Trucky]

Suggest another videos with pushbuttons: what about pushing for stay on/off, press short and long, press x times to do this and y times to do that in 5 seconds, ....

[SgtDangerWaffles]

im not sure if this is right but it worked for me insted of == i put a single - and it does the same this.

[oonmxrs]

This code doesnt work. not convert 'digitalWrite(12, 1)' from 'void' to 'bool. How to FIX????

[ArzenikRawr]

I made it so when pressed green led goes on when not pressed red led goes on

[marvelqueen]

It worked in tinkercard but it didn't work in real life

[rrssmooth]

gee I wish when people write the code, they make it bigger to be able to see the code.

[__KursK__]

Couldnt you just use the button as an circuit breaker instead of using code? Seems simpler but the code one is cooler

[RJkatztabby]

I copied the code and it won't compile. This is bullshit!
